DASV08-30 Spool, 3-Way

DESCRIPTION

A solenoid-operated, 3-way, direct-acting, spool-type, screw-in hydraulic directional valve.

OPERATION

When de-energized，DASV08-30 allows flow from ② to ① while blocking flow at ③ .When energized, the cartridge’s spool shifts to open from ③ to ②,while blocking flow out ① . While port ① may be fully pressurized, it is not intended to be used as the inlet.
Operation of Manual Override Option: To override, push button in and twist counterclockwise180° . The internal spring will push
the button out. In this position, the valve may be only partially shifted. To assure full override shift, pull the button out to its fullest
extension and hold it in this position.To return to normal valve function, push button in, twist clockwise 180° , and release. Override will be detented in this position.
